Construction Process of Container Houses

The construction process of container houses mainly includes four stages: design planning, factory prefabrication, on-site installation, and post-maintenance.

I. Design Planning Stage
Determine the number of containers and their assembly method based on usage requirements. For example, using 2-3 containers for assembly or staggered stacking can expand functional areas such as living rooms, bedrooms, and bathrooms. Simultaneously plan for lighting and insulation design, such as installing large floor-to-ceiling windows and roof skylights to enhance lighting, adding internal insulation layers to walls/roofs, and selecting triple-glazed windows to improve thermal insulation. Also consider courtyard layout, enhancing overall aesthetics and practicality through exterior facade beautification (such as paint spraying, glass curtain walls) and independent foundation design (elevated on pile foundations).

II. Factory Prefabrication Stage

1. Steel Structure Frame Fabrication: Cut and weld steel into chassis, columns, and roof ring beams. For example, a 3m6m container chassis is welded using 14050 channel steel, with crossbeams made of 482.0 square steel, and columns and ring beams using 552.0 square steel for full welding.
2. Enclosure System Installation: Wall and roof panels are assembled using 50mm thick purification panels, with an 18mm construction template load-bearing layer laid on the chassis. Standard-sized doors and windows are reserved (such as 9301000 sliding windows, 9302000 color steel plate doors).
3. Internal System Embedding: Complete the pre-installation of water and electricity pipelines, lighting fixtures, switch sockets, and air conditioning holes. High-grade floor leather is laid on the chassis floor to enhance living experience.
4. Corrosion and Fire Protection Treatment: The cut and welded parts of the steel structure need to be polished and coated with epoxy primer + topcoat. Wall panels are selected as fire-resistant polyurethane sandwich panels to ensure durability and safety.

III. On-site Installation Stage

1. Module Lifting and Assembly: Transport the prefabricated container modules to the site and complete the assembly using lifting equipment, focusing on waterproof sealing of the joints between containers (using glass curtain wall waterproof glue).
2. Detail Finishing Work: Install window security grilles and check the sealing of doors and windows, roof gutters, and other areas to ensure no leakage risks.

IV. Post-maintenance Stage

1. Rust Prevention: Regularly inspect welds, corners, and other rust-prone areas. In humid southern regions, recoat with anti-corrosion paint every 7-10 years, and every 3-5 years in coastal areas.
2. Waterproof Seal Renewal: Replace the sealant around doors and windows and at joints every 5-7 years to prevent rainwater infiltration.
3. Condensation Prevention: Reduce internal condensation within the container by using internal insulation layers and ventilation design to extend service life.
